java - SSHJ- key 对登录到EC2实例

我有一个pem文件，看起来像SSHJ测试中的文件(尽管我看不到它被引用):https://github.com/shikhar/sshj/blob/master/src/test/resources/hostkey.pem。只是尝试通过pem文件将身份验证到EC2实例(以字符串形式读取)，但是遇到了麻烦。有人这样做吗？

    SSHClient ssh = new SSHClient();
    ssh.connect("ec2-XXXXXXX.compute-1.amazonaws.com");
    ssh.authPublickey("ubuntu", getPemAsString("/Users/me/ec2.pem"));
    final Session session = ssh.startSession();
    session.exec("echo -e \"test\" >> /home/ubuntu/testfile");

错误如下:

编辑:仍然没有运气。 AWS为登录生成的私钥一定在做错什么吗？

 SSHClient ssh = new SSHClient();
 ssh.connect("ec2-XXX.compute-1.amazonaws.com");
 ssh.addHostKeyVerifier("dd:9c:XX:fa:6a:XX:32:6a:2b:c3:e7:bd:2b:15:26:5f:76:b6:‌​c4:fe");
 ssh.authPublickey("ubuntu", getRSAPrivateKeyAsString("mypem")); // Must be wrong?

 final Session session = ssh.startSession();
 session.exec("echo -e \"test\" >> /home/ubuntu/testfile");

最佳答案

在我将BouncyCaSTLeProvider添加到java.security.Security类之前，给出的用于连接EC2的示例最初不适用于我。对我有用的简单示例(为简单起见，用Groovy编写)是:

@Grab(group='net.schmizz', module='sshj', version='0.8.1')
@Grab(group='org.bouncycastle', module='bcprov-jdk16', version='1.46')

import net.schmizz.sshj.*
import net.schmizz.sshj.userauth.keyprovider.*
import net.schmizz.sshj.common.*
import net.schmizz.sshj.transport.verification.PromiscuousVerifier
import net.schmizz.sshj.connection.channel.direct.Session
import net.schmizz.sshj.connection.channel.direct.Session.Command

import java.security.*
import java.util.concurrent.TimeUnit

Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());

client = new SSHClient()
client.addHostKeyVerifier(new PromiscuousVerifier())
client.connect("ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com")

PKCS8KeyFile keyFile = new PKCS8KeyFile()
keyFile.init(new File("/dev/ec2/key/mykey.pem"))
client.authPublickey("ubuntu",keyFile)

final Session session = client.startSession()
final Command cmd = session.exec("whoami")
String response = IOUtils.readFully(cmd.getInputStream()).toString()
cmd.join(10, TimeUnit.SECONDS)

println response   //ubuntu

session.close()
client.disconnect()
